When 1 kg of ice at `0^@` C melts to water at `0^@` C, the resulting change in its entropy, taking latent heat of ice to be `80 "cal/".^@C` is ____

A

`273 "cal"/K`

B

`8xx104"cal"/K`

C

`80"cal"/K`

D

`293"cal"/K`

Text Solution

Verified by Experts

The correct Answer is:
D

Change in entropy `dS=(dQ)/T`
`therefore DeltaS=(DeltaQ)/T=(mL_f)/273`
`therefore DeltaS=(1000xx80)/273`=293 cal/K
